Small network connectivityissue

by InStyle76 / October 9, 2004 9:26 AM PDT

I have a DI-624 4-port wireless router. 1 comp was wired and 1 is wireless. The wired comp lost connectivity to the network (no internet, can't ping router or other computers) overnight. I didn't install anything or change any settings that I know of. Here are some points:

* switching ports didn't help, so it's not the port
* switching cables didn't help, so it's not the cable
* all other devices wired to router (Xbox, PS2, internet phone) as well as my wireless comp work fine, so I -think- it's not the router
* switching from wired to a wireless bridge got connectivity back, so I -think- it's not the NIC

Anything else I can try?

What does ipconfig show?
Are the lights on the NIC lit as well as the port light on the router?

IPCONFIG shows the usual:
IP 192.168.0.101
Subnet 255.255.255.0
Gateway 192.168.0.1

Light on the NIC is on, as well as the respective port on the router.

According to your figures you ahould be on the right track. I would next restart the computer in Safe Mode with Networking and see if you can connect from here. If so your problem is likely due to some spy/mal/ad ware that is interfering with communication.

Just to clarify, my comp can access the internet/LAN when connected to a wireless bridge (DWL-G820 I think) but not when connected directly to the router. I'll try booting up in safe mode + Networking once I get done doing some other things. Anything in particular I should to troubleshoot try while I'm there?

What occurs when you run ipconfig/release, then ipconfig/renew from a command prompt?

I tried a System Restore back a couple days, and still get nada when wired, so I'm going back to thinking it's the router. When I rebooted after System Restore and was wired, I did an IPCONFIG and the IP address was set at what my ISP assigned to me. When I did a release/renew, it gave me this msg:
An error occurred while renewing interface Local Area COnnection : unable to contact your DHCP server. Request has timed out.
I was not able to access the LAN.

When I undid the restore, rebooted w/ networking and had the wirelessconnected. I got the regular info:
IP - 192.168.0.101
Gateway - 192.168.0.1

When I switched from wireless to wired and did a release/renew, the same numbers came up, but I was no longer able to access the LAN or ping the router.

After reboot in safe mode w/ networking, pretty much the same things happened. I started w/ wireless connected and could access the LAN. I switched to wired, did a release/renew, got the same numbers as above, but I was no longer able to access the LAN or ping the router.

Not sure what else to try except replacing the NIC or router to see if there is a hardware problem. Tech Support at D-link didn't help much btw. They concluded that since none of their troubleshooting could resolve the issue, it must be a problem w/ the NIC or a TCP/IP issue with my computer (??). Given all that I've tried so far, I'd be willing to bet replacing the router would solve the problem.

I can make but two more suggestions:

1) Update the firmware on the router.
2) Replace the router.

The firmware is the latest available. I'm going to whine at the tech support guys one more time, and maybe I can get them to offer to fix/replace the router. I probably won't take them up on it, as that would take my network out of commission for too long to be justifiable, but just getting them to admit they were wrong would be satisfaction enough. Happy Hopefully by the time the router craps out, there will be some newer models out and I can consider it an upgrade instead of a replacement.
